Answer:
A). They grow more fearful.
Explanation:
As per the question, if the walls in the narrative turn to grow higher and become more challenging for the characters to climb, the characters are more likely to grow negatively and turn more 'fearful, distressed, and melancholic.' <em>These rising walls increases the obstacles in their life and arrest their liberty and peace which often leads to their involvement in unexpected acts in attempt to reach it which results in evoking unwanted consequences</em>. Thus, they turn more paranoid if the challenges keep on approaching. Hence, <u>option A</u> is the correct answer.
